Tropical Storm conditions are expected on the Big Island through early Sunday. Winds are expected to be strongest downslope of higher terrain, over headlands, and through passes.

Hone is expected to produce storm total rainfall of 6 to 12 inches over mainly windward and southeast-facing slopes of the Big Island, with locally higher amounts possible. Rainfall totals of 2 to 4 inches will be possible over portions of the smaller islands, mainly windward.

Surf associated with large swells generated by Hone will continue through Sunday as Hone continues westward. Expect dangerous conditions with life-threatening surf and rip currents.
